杰青 |更新由`select`选择的数组元素

在 JSON 数组中，我想根据节点的值选择一个数组元素，然后更新同一数组元素中的不同节点。例如。在下面的 JSON 中：

{
"apiVersion": "vlabs",
"properties": {
    "orchestratorProfile": {
    "orchestratorType": "Kubernetes",
    "orchestratorRelease": "1.7",
    "orchestratorVersion": "1.7.10",
    "kubernetesConfig": {
        "kubernetesImageBase": "gcrio.azureedge.net/google_containers/",
        "clusterSubnet": "10.105.208.0/20",
        "networkPolicy": "calico",
        "nonMasqueradeCidr": "10.0.0.0/8",
        "maxPods": 110,
        "dockerBridgeSubnet": "172.17.0.1/16"
        "addons": [
        {
            "name": "tiller",
            "enabled": true
        },
        {
            "name": "aci-connector",
            "enabled": true
        },
        {
            "name": "kubernetes-dashboard",
            "enabled": true
        },
        {
            "name": "rescheduler",
            "enabled": true
        }
        ]
    }
    }
}
}

我想禁用所有不是“重新调度程序”的插件，即设置.enabled = false对于数组的元素.properties.orchestratorProfile.kubernetesConfig.addons[] where .name != "rescheduler"。我能算出的最接近的是

jq -r '.properties.orchestratorProfile.kubernetesConfig.addons[] |
  select (.name != "rescheduler" ) | .enabled =  false'

但是这个，或者我尝试过的任何其他方法，我总是会丢失数组之外的数据。

预期结果是：

{
"apiVersion": "vlabs",
"properties": {
    "orchestratorProfile": {
    "orchestratorType": "Kubernetes",
    "orchestratorRelease": "1.7",
    "orchestratorVersion": "1.7.10",
    "kubernetesConfig": {
        "kubernetesImageBase": "gcrio.azureedge.net/google_containers/",
        "clusterSubnet": "10.105.208.0/20",
        "networkPolicy": "calico",
        "nonMasqueradeCidr": "10.0.0.0/8",
        "maxPods": 110,
        "dockerBridgeSubnet": "172.17.0.1/16"
        "addons": [
        {
            "name": "tiller",
            "enabled": false
        },
        {
            "name": "aci-connector",
            "enabled": false
        },
        {
            "name": "kubernetes-dashboard",
            "enabled": false
        },
        {
            "name": "rescheduler",
            "enabled": true
        }
        ]
    }
    }
}
}

我该怎么做呢？提前感谢任何想法、帮助或指导。

除了缺少一对括号之外，您的 jq 查询是准确的：

(.properties.orchestratorProfile.kubernetesConfig.addons[]
 | select (.name != "rescheduler" ).enabled) = false

也就是说，在赋值的LHS上，需要指定需要更新的值的路径。
